Android Based Moving Message Display

Abstract

The project's goal is to create a moving message display with LEDs that can be operated from an Android smartphone. The suggested solution connects an Android phone to an LED display board via Bluetooth technology. The goal of this project is to create an embedded system that uses an Android Bluetooth module to instantly display information using LEDs. All information and advertisements in the modern era are shown digitally. These days, computerized moving displays are used in large stores and retail malls. Everything, including the platform number and ticket information, is displayed on a digital moving display at the bus stops in the train station. However, they can use this project to send a message using Android Bluetooth to these displays if they would like to update the message. It shows anything it wants to deliver messages concerning important matters in the shortest amount of time. Billboards, business signs, and many other applications are just a few of the various uses for LED displays. It has been often utilized in destination signage on public transportation vehicles in recent years. Single line displays and multiline displays are the two types of display systems. LED lights are organized in two sets of 16 rows by 32 columns on a conventional LED display board, with each led positioned at a 5mm pixel. Multiple of these basic components can be combined to create display boards of any length and width. Any type of message, including alphanumeric, numeric, and so on, can be shown on these display units in both static and moving formats. A matrix display panel with a red color makes up this system. An executive program that utilizes the Arduino is also included.
